Hi
Yes, this is possible, however it needs modification. The I ordered this feature, and the dev. team made this for me withing no time.
Heres my post regarding this feature:

Basicly this version will make it able for you to specify the category ids in module (backend with a comma seperated textfield), and it will then only show events taking from those specified categories.
This is an amazing feature, will make this mdule extremely flexible.
According to Tuan,t his will be included in next release, but im sure you can figure something out with them, if you need it right away
